FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 448,885, dated March24, 1891.

Application filed September 1'7, 18%- Serial No. 865,242. (No model.)

To all whom it may (07L067lb1 Be it known that I, MORRIS \V. MOORE, acitizen of the United States, residingat Springfield, in the county ofHampden and State of Massachusetts, have invented new and usefulImprovements in Fountain-Pens, of which the following is aspecification.

This invention in self-feeding fountainpensparticularly relates to thedevices for regulating the how of ink from the barrel or ink-reservoirto the pen; and the invention consists in the combination, withthepen-barrel provided with a tip having a passage longitudinallytherethrough, of a feed-bar in said passage and extended into thechamber of the barrel and also forwardly to the pen having alongitudinal groove, and a valve consisting of a collar encircling andmovable on said bar and provided with a tongue which fits within saidfeed-bar groove, all substantially as will hereinafter more fullyappear.

In the drawings the present improvements in fountain-pens isillustrated, Figure 1 being an enlarged longitudinal sectional view ofthe fountain-pen, taken through the back of the writing-pen. Fig. 2 is across-section taken on the line 2 2, Fig. 1; and Fig. 3 is acrosssection taken 'on a line 3 3 of Fig. 1.

In the drawings, A represents the barrel and reservoir of the pen,usually constructed of hard rubber, the upper endof which is closed, andits opposite end is also closed by the tip B, which screws thereinto,being removable for the purpose of filling the reservoir with ink and topermit of the adjustment of the valve, as below described. The tip isprovided longitudinally thereof with a passage a, which leads from endto end thereof, the outer extremity of the tip being chambered for theinsertion of-the pen I) and the spring-bushing d, of cylindrical form,for retaining the pen by its shank in place in said chambered tipextremity. The feed-bar D is longer than said tip and extends throughand closely fits and practically fills the longitudinal passage therein,its forward end extending to and upon the under side of the pen near itspoint, while the rear end is projected above the tip into the reservoir.The feed-bar is grooved from above the place of its entrance into saidpassage through the tip, the said groove f extending along the tip tothe under side of the pen, being open to the forward end of the feedbar.Upon said feed-bar above the inner end of the tip is a valve, whichconsists of a collar g, adapted to encircle and slide on the bar,internally provided with a tongue or rib h, which fits the said feed-bargroove, forming, as it were, a gate or partition therein. It is apparentthat if the said collar is slid down against the upper end of the tipthere can be no ink-flow from the reservoir down the feed-bar groovethrough the tip to the pen, while the farther the internally-ribbedcollar is slid away from the end of the tip the greater will be thefreedom of ink-flow, the copiousness of such flow being very nicelyregulated, according to the requirements of the writer.

I claim- 1. In a fountain-pen, the combination, with thereservoir-barrel provided with a tip having the writing-pen therein andwith the longitudinal passage through same, of a feedbar practicallyfilling said passage and extended into the reservoir above the tip andalso forward to a contact on the pert, having the longitudinal grooveand valve consisting of a collar encircling and movable on said feed-barand provided with a tongue which fits within saidfeed-bargroove,substantially as and for the purpose set forth.

2. A feeder for a fountain-pen, consisting of a bar having agroovetherein and running longitudinally thereof to its forward end and acollar encircling and movable on the bar and provided with the tonguewhich fits said groove, substantially as described.

In testimony that I claim the foregoing as my invention I have hereuntoset my hand in presence of two subscribing witnesses.
